"There is no proposal to probe into the spying...," Haribhai Parathibhai Chaudhary told Lok Sabha on Tuesday.

The Minister said a large number of files relating to Netaji, including those relating to Khosla Commission and Mukherjee Commission, have been already declassified and sent to the National Archives of India.

There are, however, some classified files with the central government and some files are with the West Bengal government relating to Bose, Chaudhary added.

A controversy recently broke out following reports that Netaji's family was kept under surveillance by the IB for 20 years, much of it during the tenure of Jawaharlal Nehru.
